One of our active contributing users, Danno (>'.')>, made an awesome course concept where all the courses were on 1 "map" and this was copied with different start points and saved into a playlist to essentially allow you the traditional mini golf feel of 18 small holes in one large area. This was awesome but we found an issue with having so many flags in the hole at the same time which caused a game crash. This is now fixed so everyone may now enjoy the SwayzeExpress!
UPDATE:
Looks like 1.2.4 is causing some problems with progressing to the next hole (people are getting stuck after finishing a hole). We've rolled the Steam branch back to 1.2.3 version of the game to fix it temporarily while we fix the 1.2.4 "next hole" bug. I don't recommend playing SwayzeExpress until after we've addressed the issue and pushed another version out.
UPDATE 2:
We've just pushed the fix for this. BuildID 1853745. Thanks everyone!
